Helmet Concept Art -Random Sketches-

I've been roaming the interwebs for a while now.....looking for places where i can try to make some sci-fi concepts, didn't matter how.... I just wanted to feel good doing what i like, making possible the vision of those who would comission my work, BUT I've hit the big wall called "making a portfolio so that people could see my earlier work" -a big - and decided that this summer is going to be dedicated to my portfolio making .
Going further and further with what I draw....I look back at previous work and don't see them to be at the same height as the last ones. I know every new piece of art you draw will be better than the previous-I know- but bear with me. Luckily, in a few weeks I'll host a concept art workshop with some colleagues. ( got to get a tablet too.....so i could do digital art on my own tablet, I don't like depending on other's stuff >.> )
Hope i can work up on my portfolio while doing that. And i sincerely thank everyone how visits my drawings. ^_^
